Each case is different, though; so lets take a look at this particular claim. First off, what is Pyriproxyfen? Basically, its a pesticide that is effective against a wide variety of arthropoda (insects). Specifically, its a a juvenile hormone analog that prevents insect larvae from developing into adulthood and thus renders them unable to reproduce. It was introduced into the US in 1996 to protect crops against the whitefly.
Now heres the thing. Its not as though pyriproxyfen hasnt been well studied. The WHO even has a web page with its guidelines for pyriproxifen in drinking water. A great deal is known about its physiochemical properties, toxicology, and safe levels. Specifically, the WHO recommends that the dosage of pyriproxyfen in potable water in containers should not exceed 0.01 mg/L under the WHO Pesticides Evaluation Scheme. More specifically:
...
I would also add that Brazil would have to have been using truly massive doses to exceed the acceptable daily intake, not to mention that humans do not make or use sesquiterpenoid hormones (a.k.a. insect juvenile hormones), which is what pyriproxifen targets. Finally, one cant help but notice that Doctors in the Crop-Sprayed Towns is anything but an objective group. Its been around at least since 2010, and its message has always been the same dating back to 2010: That pesticides cause spontaneous abortions, infertility, congenital malformations, and a wide variety of disorders. In other words, this is a biased report from a biased group presenting no evidence to back up its conclusions. Its all speculation based on a fear of pesticides.
...
There are lots of conspiracy theories out there. Theres lots of pseudoscience out there. Whenever something like the Zika virus makes it into the news, you can be absolutely sure that conspiracy theories based on pseudoscience will inevitably follow. Thats why its so critical to do a little research before sharing something like this. When you have such an enormous social media platform, you owe it to your fans not to use it to spread misinformation like this."

And yet this nonsense is getting play at DU, and I suspect it will get more.
